Windows 7: Svchost.exe Crazy High CPU Usage and Crazy High Memory Usage

Try ThrashZone's suggested update first. After applying that update I'd personally suggest disabling Windows Update service for 24 hours before re-enabling it the next day then rebooting and running a check for updates.

How did you disable Windows Update Service? Like this?

The correct way is stop the service then set it to disabled. Maybe you used msconfig to prevent it from starting?

Stopping or disabling Windows Update Service should not cause software crashes.

The programs crashing was not caused by disabling windows update, it was caused by a bios mod I recently installed and I got the infamous blue screen errors too

Sometimes I hear one of the PC’s fans running fast as if it’s working hard to cool the CPU. Sometimes this happens after visiting a single website. Other times I can use the PC for an hour or two & this does not happen.

When it happens the Windows Task Manager shows CPU usage at 25%. The Resource Monitor shows the same for svchost.exe (netsvcs), PID #336, Host Process for Windows Services, at 25%.

What would cause this to be so high, especially when it happens from just looking at a single website? And it typically stays at 25% while I’m using the PC. After a period of non-use the CPU usage will be back down to 1 or 2 percent.

One time I ended the svchost.exe (netsvcs) process & don’t recall any ill effects. But another time I had to re-boot the PC to get it working again.

In the Task Manager > Services window, PID 336 shows up 16 times with different names, and none of them with the name “svchost”. However the Group column has them all listed as “netsvcs”.

I had 3 instances of MSWorks open & Windows Explorer open & my CPU usage is 25% while composing this message.

I have Windows Updates set to download when I tell it to so I don't think this is the problem.

How do I know which one is the culprit & what to do about it?

Have the same issue. svchost starts randomly (and I mean it!), no matter what I'm doing or do nothing, then consume over 50% performance for tenths of minutes and suddenly kill itself and then nothing. Doesn't matter if I set low priority in task manager, and put higher priority for what I want to do, it slowing down whole computer and make lags of everything anyway. Not even single stupid video on u2b can be played smoothly. updates - turned off.
any idea?
except reinstall whole comp, I did it month ago and have installed minimum sw, but almost commit suicide until that heap of updates finally installed. and I let to install only those really important and just few optional. pls check attached picture.

I ran sfc /scannow three times in a row and restarted after each run. No problem was found so I'm still wondering what is going on.
